and not cut or injure the tire, and the rim will be strong and durablealthough of relatively light weight.

A feature of the invention consists in combining a rather thin rim andtwo rows of inwardly extending wire spokes spaced apart from each otherat the rim and crossing each other near the rim and having reinforcingmeans on the-inner surface of the rim between the two series of wirespokes, whereby such reinforcement is confined to the point of stressand the stress or pull of the spokes is located on each side and closeto said rein'.-' forccment and the direction of pull'of the spokes isinclined toward the reinforcement.

The-nature of the invention will be understood from the accompanyingdrawings and the following description and claims:

In the drawings, Fi ure 1 is a side elevation of the upper hal of suchwire spoked wheel. Fig. 2 is a section on the line 2-2 of Fig. 1, with aortion of the rim and spokes removed. F1 8 is a section throu h aportion of the run showing the spo e mounting on a large scale, Fig. 4is a perspective view of one of the wire spokes broken away betweenits'ends.

There is shown herein the rim 10, hub 11 and the spokes 12 of a wirespoked wheel. The s okehas an inturned end 112 which is insertibleradially into the side of the hub and the spoke extends tangentiallyfrom the hub to the rim and, therefore, the spoke is non-radial. Thereare two series of such spokes, one secured to each lateral portion ofthe hub, as shown in the lower part of Fig. 2, and, therefore, on eachside of the radial plane through the wheel. These spokes are arranged intransverse pairs and the spokes of the two series cross each other nearthe rim and at the outer ends extend through the rim and are headed toprevent withdrawal from the rim.

One advantage of a vehicle wheel of this type is its lightness inproportion to its strength and for accomplishing that purpose moreefi'ectively, this invention contemplates a relatively thin light rim 10with an annular reinforcing bar 13 secured to the inner surface of therim between the two series of wire spokes, as shown in Figs l and 2. Theouter ends of the two series of wire spokes are secured to the rim atpoints not very far apart so that the outer ends-0f the spokes at theirattachmentwith the rim are adjacent tothe op osite sides of thereinforcing bar 13, pre erably as close as possible and since the spokesincline so as to cross each other in a non-radial way, as shown in Fig.2, the spokes almost touch 'the inner edges of the reinforcing bar 13.Therefore, preferably the spokes are located as close to the bar aspossible for the purpose of limiting the width of the reinforcing bar 13and getting. from the construction the greatest possible resistance andstrength of the rim and reinforcin bar with the least possible weightandthis is attained by having the reinforcing bar between the spokes andhaving the spokes and their attachment to the rim as close to thereinforcing bar as possible.

For the purpose of attaching or securing the s okes to the rim so thatthe connection will e strong andyet the structure furnish a smoothexternal rim surface so as not to injure the tire, the spokes have anenlarged fore, the outer surfaces of the spoke-heads 15 aresubstantially at a right angle to the ra dial line of the wheel.Likewise the body of the head and the recess 16 or the spoke hole areatan inclination, as shown in Fig. 3.;

' Since the spoke is arranged tangentially of the hub and crosses theother series of spokes, the head of the spoke bears a .peculiarrelationship to the extension 112 on the inner end of the spoke, asindicated in Fig 4. 7

he invention is:

1. The combination with a hub and rim of a vehicle wheel, of a pluralityof series of head 15 on their outer ends and which may 1 spokesconnected with saidrim and spaced from each other, and an annularreinforcing means provided on the inner surface of the rim between theseries of spokes substantially as and for the purpose set forth.

2; The comhination with the rim and hub ofe vehicle wheel, of two seriesof spokes, the spokes of the two series crossing each (ii-11613andreinforcing means provided on the inner surface of the rim betweenthe two series of spokes.

3. The combination with the rim and hub of a vehicle Wheel, of twoseries of spokes, each series of spokes extending from the hub on oneside of a radial plane through the wheel to the rim at the other side ofsuch plane so that the two series of spokes will cross each other, and areinforcing bar secured to the inner surface of the rim between the twoseries of spokes.

4. The combination with the hub and rim of a vehicle Wheel, reinforcingmeans provided on the inner surface of the rim, and two series of spokesconnecting the hub and rim, the spokes of the two series crossing eachother and-being held in the rim adjacent the opposite sides of saidreinforcing means. i y

In witness whereof, I have hereunto af fixed my signature in thepresence of the witnesses herein named.
